From f8e6710de859e1ac3a5df294bddeca19f60cec9a Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Sun, 7 Aug 2016 17:28:26 +0200 Subject: [PATCH] perf hists: Introduce nr_header_lines into struct perf_hpp_list Currently we support just single line headers, this is first step to allow more. Store the number of header lines in perf_hpp_list, which encompasses all the display/sort entries and is thus suitable to hold this value.
